SELF-THRE-ADIN Loom-SHUTTLE. V

To all whoin 't may concern: I I

Be itlmown that I, PIERRE P. DAUDELIN, a ci'zen oi the United States,'residing at Fall River-,cdunty of Bristol, State of Massa ohusetts, have invented an Improvement in Self-Threading Loom-Shuttles, of which the following description, in connection with the I This accompanying drawings, is a specification, like letters on the drawings representing like parts. I g I invention relates particularly to what are technically termed self threading shuttles for looms, wherein the thread is led into the delivery-eye by means so arranged as to prevent its subsequentescape therefrom and consequent unthreeding of the shuttle;

The objects of my invention are to provide a strong, durable, efiicient, and cheap shuttle of the type referred to and which can be easily and quickly threaded, and accordingly. I have by a very simple device inserted in the shuttle, cooperating with slots or pas-, sages in the latter, efiected the desired result, the novel features of my invention being fully described'in the suhjoined specification and particularly pointed out in the following claims.

Figure 1 is a side elevation of the threaddelivei ing endof a shuttle embodying my invention. Fig-Zisato or lain view thereof, showing the shuttle t rea ed. Fig. 3 is .a perspective view of thepart of the "shuttle shown in Frigsfl and 2. Fig. 4 is a transverse section taken on the line 4 4, Fig. 2, looking toward the left, the thread-conductor being shown in elevation; and Figs. 5 and 6 are two perspective views, detached, of the thread-conductor, to be described.

The shuttle-body 1, of usual construction, has a bobbin-recess 2 and a threading-recess 3 at the front end thereof and communicating therewith bya wide cut or channel 4 in alinement with the tip of the bobbin 5, Fig. 2. A hole 6 is bored through the shuttle-body transversely and artly intersecting the recess 3; one end 0? the hole constituting the side delivery-eye of the shuttle, the side wall of the shuttle being longitudinally recessed or scooped out at? (best shown in Figs. 1 and 3 and in-dotted lines Fig. 2) adjacent the eye to leave a thread-s11 port or shoulder 8 partially crossing the elivery-eye. The ,shuttle'body forward of the hole 6 is slitted Specification of Letters Patent. Applioationfiledhiarch6,1905. tam... 248,414.

Y The shuttle-body is cut away at theforward 6o portion of. the intersecting passages 9 and 10, as at 1,1, to leave a horn 12,11nder which the 7 thread, asses when the'shuttleis threaded,

A longitudinal slot 18 extends t is length of the body 13 and is enlarged at its inner'end by'8o cross-cutting the neck 15at-19'and enlarging the upper and lower portions'of the crosscut, as shown. The body is externally out awa 0r recessed adjacent the slot 18st 26, t

so t at when the conductoris in. position a clearance-space is left between it and the wood oi: the shuttle body just above and e tending the length; of the slott Nh-en the conductor is so positioned, the slot is at the bottom, its outer end terminating behind and below the thread-support or shoulder 8, and the threadassage 9 opens into the clearance 20 the ength-or'the slot, while the cross i cut 19-stands upright and open toward thepoint of the shuttle, as shown in 2.

In threading the shuttle the thread 21 is first drawn forward into the channel 4 and recess 3 and thence into the slit or passage 10 (the walls of which are inclined longitudinally and also with relation to the sage 9) and then under the horn 12 into the passage 9 beneath the horn. By a rearward pull the thread is then drawn ale 6 the passage 9 into the clearance 20 and t enoe passes into the conductor and the delivery :05
